Reliable products suited to your needs

TrainWise® products are a continuum ranging from simple sensors to powerful servers. Train architectures are as diverse as the authorities running them. Quester Tangent meets the demands of modern specifications by intelligently combining products into packaged solutions. To help navigate our product offerings, we categorize our products by function. Product classes include servers, controllers, peripherals, and sensors.

Servers

Servers are central processing units installed on trains to perform multiple services. They have the highest level of capability and can run different applications simultaneously to manage train subsystem network communications, control and diagnostics, and databases. Train Control and Monitoring Systems and Train Passenger Information are built around servers facilitating centralized management of all train subsystems.

Controllers

Controllers are electronic subsystems dedicated to a specific service, such as Event Recorder, I/O Controller, or Public Address Amplifier. Controllers interface to the real world through electrical I/O and sensors to obtain train status and drive the operation of connected equipment. They also communicate with each other and central servers through onboard networks.

Peripherals

Peripherals are support devices that provide a flexible product configuration to deliver a cost-effective project within rigorous requirements. These peripherals often include off-the-shelf or specialty items that are integrated into a Quester Tangent solution.

Internal announcement signs, route maps, and external destination signs are seamlessly integrated into rail passenger information systems and are designed for flexibility to meet broad new vehicle and retrofit applications.

Quester Tangent supplies ancillary systems as required to meet obligations of a full technology package:

Car ID modules

Network testers

Protocol analyzers

Sensors

Sensors are attached to controllers or peripherals to monitor and capture data. Quester Tangent typically purchases sensors and integrates them to create a compliant system. Sensors that are commonly integrated include:
